Pitches to cut worldwide greenhouse gas emissions by 80 percent by 2050 are too leisurely and must be brought forward by decades, Lester Brown, president and founder of the Earth Policy Institute in Washington, said Friday at a symposium in Tokyo.
"We are going to have to move much, much faster. I think the game will be over long before 2050," the environment expert said at Sophia University.
Prime Minister Yasuo Fukuda is expected to release a new initiative on environmental preservation Monday in which Japan will propose reducing long-term its own greenhouse gas emissions by 60 percent to 80 percent from current levels by 2050. The initiative will not touch on medium-term goals.
